#4Mk2 Accuracy Adjustments ?

Post by Vandervecken »

What can be done to a #4Mk2 to help it get its best accuracy ? I am thinking along the lines of stock and or barrel shimming and action torque specs. Its already pretty accurate. I like bringing out the best in a firearm which is why I ask. Thanks for any ideas.

Tinker with the stock and ammo- reload to perfection, and a good set of eyes helps, I am way too old and can no longer see out to 500 yards. I just shoot and have fun. It will be interesting what the real shooters have to say. :shifty: You also have to measure barrel bore wear and muzzle wear- a like new barrel is helpful.

Maybe this newer book also. I do not have either book.

Great response 72 usmc! I might check out some of those resources myself.

Setting it up properly in the first place.
How well is it bedded? Where is the barrel bedded?
is it all matching?
Does the end f the barrel sit in the bottom center of the stock with 4~7 Lbs of pressure?
How accurate do you call "pretty accurate"?
Are you hand loading for it?

It was a out of the wrap & de-cosmoed new #4 Mk2 Fackersley. I removed the rear sight [and carefully saved the parts] and mounted a scope. No bedding-yet. Out last fall it did a 2" and maybe a bit better at 100yds with a 174gr Hornady hpbt Match with 37.7 gr of IMR 4064 at 3.075 col. I did a bit of polish on the trigger points - which helped. All secured and action screw torqued to 50" lbs. When all was clean and assembled correctly , I noticed when I grabbed the barrel it had noticeable free play between the fore stock and the hand guard. NORMALLY a free float on a barrel is a good thing. BUT some rifles don't like that barrel floppin around. SO I was thinking maybe a cork type shim at the stock channel front - like they do to mosins - to slow the vibes down a bit.

If the action screw is tight, the noxx form is bedded over the first 1 1/2" for the bottom 1/3 of the radius & the barrel is free floated except for the "pad" at the muzzle (producing the 5~7 Lbs of centered upthrust), end then its good.

A 10 round 2" circular group @100 yds is actually very very good. (they're designed for almost 3").
Center bedding could go either way. Its usually considered remedial if normal beading as I've described isn't making the grade.

It is a battle rifle not a target rifle. 2" at 100 is good for a new barrel. I would suggest you do some ladder testing with different powders. If your barrel is loose lots of linseed oil will tighten things up, do this before ladder testing.
